Vitamin D3 and vitamin K2 are often taken together because they play complementary roles: D3 supports calcium absorption, while K2 helps direct that calcium toward bone tissue.* Many adults get limited vitamin D from sunlight for much of the year, which is why a daily softgel has become a staple. Nutricost pairs a generous 5000 IU of D3 with 100 mcg of K2 in the well-studied MK-7 form.

What's inside

• 5000 IU vitamin D3 per softgel
• 100 mcg vitamin K2 as MK-7 per softgel
• 120 softgels – 120 servings, a four-month supply
• Non-GMO and gluten-free
• Made in a GMP-compliant, FDA-registered facility

How to use

Take one softgel daily with a meal that contains some fat, which helps absorption of both vitamins. One bottle lasts four months at that rate. Vitamin K can interact with blood-thinning medications such as warfarin, so speak with your healthcare provider before starting if you take one.

Why we carry it

Combination D3/K2 products often use a low K2 dose or the shorter-acting MK-4 form. This one lists both nutrients clearly, uses MK-7, and spreads 120 servings across a single bottle, which keeps the cost per day low without sacrificing dose transparency.*
